Abstract

An appliance security system to secure appliances such as air or water heaters, air conditioners, pumps, cooling, cooking or washing appliances against theft from building sites. The system includes a lock means acting on control means of the appliance, and code entry means wherein entry of the code into the code entry means permanently deactivates the lock. This is performed by an authorised person after the risk of theft has diminished.

Claims

1. An appliance security system comprising:

a controller for selectively enabling and disabling operation of an appliance,

a lock for the controller, the lock having a first condition wherein it prevents the controller from functioning, and

a code entry facility for co-operation with the lock, wherein transmission of a predetermined code from the code entry facility to the lock changes the lock to a second condition at which the lock is deactivated thereby allowing functioning of the controller whereby the appliance is secured against unauthorized use whilst the lock is in its first condition.

2. An appliance security system according to claim 1 wherein said appliance is supplied from the manufacturer with the lock in said first condition.

3. An appliance security system according to claim 2 wherein the lock may be permanently deactivated once the appliance has been installed.

4. An appliance security system according to claim 1 wherein said appliance is one of a domestic air heater, an air conditioner, a cooking appliance, a cooling appliance, a washing appliance, a vacuuming appliance, a door actuator, a filtering appliance or a pumping appliance.

5. An appliance security system according to claim 1 wherein said lock comprises an electronic lock.

6. An appliance security system according to claim 1 wherein said lock may be deactivated for a set period upon entry of a test code via the code entry facility.

7. An appliance security system according to claim 1 wherein said code entry facility comprises an electronic key separable from and communicable with said lock.

8. An appliance security systems according to claim 1 wherein said code entry facility is integrated with said controller, and said controller is remote from said appliance.

9. A method of deterring theft of an appliance fixable in a building, the appliance including a controller for selectively enabling and disabling operation of the appliance, the method comprising the steps of:

(i) providing a lock for the controller;

(ii) conditioning the lock to a first condition whereat it prevents functioning of the controller;

(iii) providing a data entry facility for use with the lock, and

(iv) conditioning the data entry facility and the lock such that entry of a first code into the data entry facility will deactivate the lock to a second position whereby it will allow functioning of the controller,

wherein theft of the appliance is deterred whilst the lock is in the first condition whereby the appliance cannot be activated.

10. A method according to claim 9 wherein a second code may be entered into the data entry facility which deactivates the lock for a limited duration.

11. A method according to claim 10 wherein the first code may be entered once the risk of theft has been passed.

12. A method according to claim 9 wherein entry of the first code permanently deactivates the lock.
